Adjuster for facemask

ABSTRACT

An adjuster for facemask comprising a lamellar structure and a plurality of stabilizing pillars on the lamellar structure, which each stabilizing pillar is comprised of a stabilizing piece installed in a stabilizing groove. When users wear facemasks, they insert ear-loops extending from one side of the facemask into the stabilizing groove of the respective-side stabilizing pillar on the lamellar structure, to be held fixed in the lamellar structure by respective stabilizing piece. Afterwards, the user places the adjuster to the back of the head and inserts the other ear-loops into their respective stabilizing grooves on respective stabilizing pillars to be held fixed by their respective stabilizing piece. Hence, the ear-loops are tucked to the bottom of the stabilizing groove of stabilizing pillar due to a pulling-force, and the facemask becomes firmly held fixed by the adjuster, wrapping around the head, which for this reason air leakage is reduced and security is heighten. Moreover, the facemask is also improved with increased comfort, by allowing user to adjust tightness on-demand.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is a device for use with facemasks, which more particularly, is such a device that makes for easy tightness adjustments of the wear, that not only has the effect of reducing air leakage consequently increasing security, but also makes for better comfort.

2. Description of the Prior Art

Due to the SARS (Severe Acute Respiratory Syndrome) outbreak, people realized the importance of effectively shielding viruses from the body. Therefore, our first line of defense in hospitals or any other kind of crowded, confined, virus-rampant place would be to wear a facemask. FIG. 1 shows a schematic diagram of the conventional facemasks, capable of shielding users from viruses. These facemasks 1 are comprised of a mask-body 10 and ear-loops 11 extending from both sides of the mask-body 10, and are donned by looping ear-loops 11 around the ears. However, users have different sizes heads while there are not many sizes for the length of ear-loops 11, thus the conventional facemasks are not fit for every user. Moreover, since facemasks 1 are not leveled to the height of the ears when worn, ear-loops have to be tightened upward, and gaps are likely to develop between the head and the facemask, easily causing air leakage to reduce security. Furthermore, if the ear-loops are worn around the ears in lengthy durations, the ears are likely to be suffering from discomfort if not be inflamed, hurting the ears of most users who have to use it in long durations. And lastly, if users use common head-loop facemasks, such as ones of N95, the users must greatly extend ear-loops to loop around the head and adjusting the angles afterwards. The usage of the head-loop facemasks, along with other conventional facemasks mentioned, are inconvenient and users are likely to suffer discomfort.

Hence, it is apparent that the conventional facemasks are in need of improvement due to those many drawbacks.

Thus, the inventor spent several years improving the conventional facemask in view of these drawbacks, and conceived the present invention.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a device that reduces air leakage in facemasks, thereby heightening security.

A second objective of the present invention is to provide a device that allows for easy, on-demand adjustments of the tightness of facemasks, making facemasks more easily donned and comfortable to wear.

A third objective of the present invention is to provide a device that has a simple structure, thus can be manufactured easily.

The last objective of the present invention is to provide a device that diffuses conventional facemasks' one-directional pressure into two-directional, spreading the pressure from few high-tensioned points into several less-tensioned points, greatly reducing the pressure at the most tensioned.

Thus, the inventor came up with the adjuster comprising a lamellar structure and a plurality of stabilizing pillars on the lamellar structure, which each stabilizing pillar is comprised of a stabilizing piece installed in a stabilizing groove. When users wear facemasks, they insert ear-loops extending from one side of the facemask into the stabilizing groove of the respective-side stabilizing pillar on the lamellar structure, to be held fixed in the lamellar structure by respective stabilizing piece. Afterwards, the user places the adjuster to the back of the head and inserts the other ear-loops into their respective stabilizing grooves on respective stabilizing pillars to be held fixed by their respective stabilizing piece. Hence, the ear-loops are tucked to the bottom of the stabilizing groove of stabilizing pillar due to a pulling-force, and the facemask becomes firmly held fixed by the adjuster, wrapping around the head, which for this reason air leakage is reduced and security is heighten. Other than this, since the facemask is worn more like a headband and user can adjust the tightness of the ear-loops on-demand through the stabilizing pillars of the adjuster, the user does not have to extend the ear-loops around the head and adjust it afterward making it more convenient, all the while more comfortable as it fits better and is less likely to cause irritations to the user. Nevertheless, the conventional facemask is greatly improved upon by this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 2, it is a three-dimensional schematic diagram of the adjuster for facemask in accordance with the present invention. Adjuster 2 comprises a lamellar structure 20 and a plurality of stabilizing pillars 21 on the lamellar structure 20. The stabilizing pillar 21 has at least one stabilizing groove 22. A stabilizing piece 23 is installed in the stabilizing groove 22. A possible shape of the stabilizing piece 23 is sword-shaped, with the sword-shaped front edges 231 of the stabilizing piece 23 coming in contact with an inner wall of the stabilizing groove 22. Stabilizing piece 23 is flexible.

FIG. 3 and FIG. 4 are respectively the lateral view and back view of the adjuster in present invention. When users wear facemasks 1 in accordance with the present invention, the users inserts ear-loops 11 extending from one side of the facemask 1 into the stabilizing groove 22 of stabilizing pillar 21 on the respective side of the adjuster 2. The ear-loops 11 then can be held fixed in the lamellar structure 20 by the sword-shaped front edges 231 of stabilizing piece 23 against an inner wall of the stabilizing groove 22. The user then places the adjuster 2 behind the head and inserts the other ear-loops into the stabilizing groove 22 of their respective stabilizing pillar 21 of the adjuster 2. It so happens now that the ear-loops 11 pushes against the stabilizing piece 23 and tucks to the bottom 221 of the stabilizing groove 22 of stabilizing pillar 21, and facemask 1 is thus firmly held fixed on the adjuster 2 by what would be described as a pulling-force. And further in addition, because ear-loops 11 of facemask 1 are pulled behind the head, the facemask 1 fits by wrapping around the user's head, thereby reducing air leakage and ultimately increasing security. Thus because the ear-loops 11 are not looped around the ears, the skin is saved from inflamation or other irritable conditions. Furthermore, since the user can also adjust the tightness of the ear-loops 11 on-demand through the stabilizing piece 23 of the adjuster 2, the facemask is made more comfortable to wear. When the user feels that the ear-loops are too tight, he only has to disengage and reengage the ear-loops to adjust for the preferred tightness.

FIG. 5A and FIG. 5B show the methods to hold fixed the facemask 1 with the adjuster 2. That is, the stabilizing of the ear-loops 11 of facemask 1 is not limited to solely being held fixed by stabilizing groove of the stabilizing pillar 21 through the pressure asserted by the stabilizing piece 23 as shown in FIG. 5A, but also by the ear-loops being looped around at least one stabilizing pillar 21 accompanying previous method. This increases the tension of the ear-loops between facemask 11 and the adjuster 2, raising the stability of the facemask 1 as shown in FIG. 5B. Another method in which stability can further be augmented is simply cross-looping the ear-loops 11 of the facemask 1 to the stabilizing pillar 21 on the alternate adjuster, making the facemask even more firmly fixed. Now other than the stability being increased, the comfort and the convenience is also increased, provided by the invention's easy donning. To explicate, as user feels uncomfortable trying to breath or speak, and would like to be relieved of the facemask 1, the user simply pulls an end of one of the ear-loops 11, loosening it from the stabilizing groove 22 of the stabilizing pillar 21 to partially remove the facemask 1 from the face. The user then turns the facemask 1 forward to drape it around the neck, making it comfortable to speak, breath, and perform many other actions, and since the facemask 1 is still close to the mouth, the user simply has to insert the ear-loops 11 in the stabilizing groove 22 of the stabilizing pillar 21 again don the facemask 1, which is as shown in FIG. 6. Thus, the present invention greatly increases the convenience to conventional facemasks. Moreover, while one side of the lamellar structure 20 is smooth to the touch, such that placing it to the back of the neck is not uncomfortable, the other side of the lamellar structure 20 can be coarse, as to prevent it from sliding down hair or hat.

Compared with that of without adjuster, facemasks used with present invention have the following advantages:

1. The present invention greatly increases comfort through the stabilizing pillars, allowing the user to adjust the tightness on demand.

2. The present invention greatly increases stability through the stabilizing piece clasping the ear-loops within the stabilizing groove.
